Objective: We aimed to estimate the proportion of patients visiting the emergency department (ED) who were not up to date with cancer screening guidelines to assess the scope of need and potential impact of ED-based cancer screening interventions.
Methods: Adult participants from the 2015 National Health Interview Survey were included. Among patients nonadherent to national breast, colorectal, or lung cancer screening guidelines, the proportion of patients reporting an ED visit within the last year was estimated, accounting for complex survey sampling design features.
